SFTPSync V1.3

In this release we have modified the file sync process to first delete existing files from the remote OpenVMS system before then uploading a new version of a file. This unfortunately slows down the initial sync process, but was necessary because we found that the SSH server in some versions of OpenVMS TCP/IP services resulted in unreliable results and corrupted files when the size of a file was reduced.

This release also addresses a problem in the underlying SSH.NET library where, if a file was edited in such a way that the contents of the file changed, but the changes resulted in a file of the exact same size, the change would not be replicated to the OpenVMS system.
